Login trouble and Enterprise Proxy use question

1. Login trouble Question
Initially, when I started using it, the code completion worked fine after completing a series of setup steps. However, after experimenting with entering the Enterprise auth provider URL address, the code suggestions suddenly stopped functioning. Restarting Xcode or re-logging into GitHub Copilot for Xcode didn’t resolve the issue.

**Describe the bug**

I’m currently logged in and did not enter the auth provider URL, but code completion remains unavailable. The page is at this location:

**Logs**
, and the logs show: NotSignedIn


**Versions**
- Copilot for Xcode: [e.g. 0.31.0]
- Xcode: [e.g. 16.0]
- macOS: [e.g. 15.0.1]

**Steps to reproduce**
1. open github copilot for Xcode, and check updated then login in.
2. open xcode xx.xcworkspace and add code, but code completion remains unavailable.

**Additional context**

2. Enterprise and Proxy use method
I have another question to ask: For security reasons, if I want to integrate our company’s internal code completion API, how should we connect it to this tool? Is it related to the previously discussed setup of the Enterprise auth provider URL and the Proxy capability mentioned below? How is this implemented? Are there any example documents or guides for replacing either the chat service or the code completion service? What steps would I need to follow?
